This time I just had a few spare parts and a day off from my usual work.
Ingredients:
(1) Arduino mini,
(1) Parallax 28018 (an SHT15 I believe), and
(1) BlueSMiRF radio.
The wiring was pretty simple, involving hooking up power to everything, connecting the sensor's clock and data lines, and of course the tx/rx pins for the modem.
